To my knowledge, the Warcraft story is being continued through World of Warcraft at the moment.
I think they'll be doing another expansion for WoW to continue the story.
I'm finish in this game. It's very fantastic games I think. I love this game.....
Starcraft II is the next big Blizzard release along with the next expansion pack for WoW. Warcraft IV is so far off that I wouldn't worry about seeing it in this life time.
WoW is going to be their device for continuing the Warcraft story for a few more years at least.
Look how long Everquest and EQ2 have been around.
I did enjoy Warcraft 3 but I didn't like how you could have so few units but that was part of the strategy I guess.
I am exited for Starcraft II and I am also excited for the expansion for WOW.
With the way WOW is going and the money they are making from it I would assume they will continue that for some time so I wouldn't expect a Warcraft IV for awhile.
From the definite success of Warcraft III, they may just release a strategy Warcraft game alongside WoW, perhaps following the same storyline World of Warcraft does?
I for one would love to see one, even though I play WoW too. I simply loved III.
